What are the main cloud migration strategies?

In the cloud migration process, organizations can choose from several key strategies, known as the “4R” or “6R” model. The choice of the appropriate strategy depends on the specifics of the organization, its business goals, and the state of current IT infrastructure. Below we present the main approaches to migration, along with their characteristics and application:

• Rehost (lift-and-shift): This strategy involves moving applications to the cloud without significant changes to their architecture or code. It is the fastest and often cheapest migration method, ideal for companies wanting to quickly move their systems to the cloud. Rehosting works particularly well for traditional applications that don’t require deep modernization. Companies using this method can expect quick results, but at the same time must be aware that they are not fully utilizing the cloud’s potential.

• Refactor: The refactoring strategy requires partial modification of application code to better utilize cloud capabilities. This is a more advanced approach than rehosting, allowing for optimization of performance and costs. Refactoring is particularly beneficial for applications that can benefit from native cloud services, such as managed databases or queuing systems. Companies opting for this strategy can expect better scalability and application performance.

• Revise (Re-architect): This strategy involves thorough application rebuilding to fully utilize the cloud’s potential. It is the most time-consuming and costly method, but at the same time offering the greatest benefits in the long term. Revise is ideal for organizations that want to completely modernize their applications, using microservices, containers, and serverless architecture. Companies opting for this strategy can achieve the highest level of flexibility and innovation.

• Replace: This strategy involves replacing existing applications with new cloud-native solutions, often in the form of ready-made SaaS (Software as a Service) services. This is a radical approach, ideal for companies ready for complete digital transformation. Replace eliminates the need to maintain legacy systems and allows full use of innovations offered by cloud providers.

• Retain: Although not strictly a migration strategy, retain means the decision to leave some applications or systems in the current environment. This may be necessary for regulatory, technical, or business reasons. Companies often use this strategy in combination with others, creating a hybrid environment.

• Retire: This strategy involves identifying and retiring applications or systems that are no longer needed or whose functionality can be replaced by other cloud solutions. Retire helps optimize the application portfolio and reduce costs.

Research conducted by leading consulting firms shows that organizations using a mixed approach, combining different migration strategies, achieve the best results. Such a flexible approach allows for IT cost reduction of even 30% and shortening the time to introduce new features by 50%. The key to success is a thorough analysis of each application and selection of the best migration strategy for each, taking into account both short- and long-term business goals.
